 broad; dorsal surface flattened and sloping forward, with bluntly connate

Vanua Levu: Labasa (Type-locality), Waimmu, Suene. 

 The irregular, very coarse carinae on the cheeks and clypeus dis- 

 tinguish the soldier. Type. — M. C. Z. 8,722. 



71b. Camponotus (Myrmegonia) schmeltzii Mayr, var, loloma, 



var. nov. Fig. 33. 



Worker. Length 4-6 mm. 



A small series of worker minors and media are very similar in structure and 

 color to schmeltzii var. kadi, but differ in the outline of the epinotum which is 

 impressed in front of the posterior angle and shows a tendency toward de- 

 veloping into a tooth as in laminatus and lauensis. This contour, even in the 

 small series before me is highly variable as shown in Fig. 33. 



Var. loloma is interesting in being one of the very few truly Fijian 

 ants that I found in the Lau Archipelago. My specimens were taken 

 in the woods near the center of the island. 



Lau: Kabara. 



71c. Camponotus (Myrmegonia) schmeltzii Mayr, subsp. 

 TROTTERi, subsp. nov. Fig. 34. 



Worker. Length 3.90 mm. 



A unique worker from the mountains near the lake in Taviuni differs from 

 the others in the contour of the epinotum and in pilosity. The epinotum, 

 in addition to sparse, long hairs, has a moderately dense covering of very fine, 

 short, erect hairs. In other respects it is very similar to var. loloma.
